There is a special form of a quadratic that is best for graphing the equation. We'll analyze it thoroughly here. Here y0 is the y coordinate of the vertex, x0 is the x coordinate of the vertex, and a is the amplitude, a measure of the thickness of the parabola.
Comments: Comments Off. According to the U.S. Geological Survey the average person uses between 80-100 gallons of water per day and estimates that 95% of the water we use, goes down the drain (1). So we waste 76-95 gallons per day. A shower, for example, uses between 2-5 gallons per minute.A dishwasher uses between 4-10 gallons of water for each load. A washing machine uses between 25-40 gallons of water every time we do a load of laundry.With just the use of basic water-using appliances, we use a lot of water. shower, for example, uses between 2-5 gallons per minute.

The energy we waste using bottled water would be enough to power 190,000 homes2. Americans used about 50 billion plastic water bottles last year. However, the U.S.âs recycling rate for plastic is only 23 percent, which means 38 billion water bottles â more than $1 billion worth of plastic â are wasted each year3. The recommended eight glasses of water a day, at U.S. tap rates equals about $.49 per year; that same amount of bottled water is about $1,400.
